Combination sled and ramp

Abstract

A device which can be used as a sled towed by a vehicle such as a snowmobile which can be converted to a ramp for loading a snowmobile or any vehicle onto a transporting device such as a truck. The device is comprised of a frame having vertical sides forming a container with a pair of skids attached beneath the frame and a tongue or hitch attached to one end for towing purposes. The sides and ends are attached in a manner which permits them to be adjusted to a position for converting the body of the slid to a loading ramp. A transition piece is attached to the end of the frame for attaching the device to a transporter for loading purposes. The vertical sides are hinged to adjust to various positions and act as guides, if desired. The frame is provided with suitable attachment devices so that the hitch or transition piece may be attached to either end.

What is claimed is:
